While the county offices were challenged only on the Republican ticket, the state superintendent of education and the U.S. Senate races had candidates from both sides of the aisle.

U.S. Senate - GOP

Two-term GOP Sen. Lindsey Graham has avoided a runoff.

During his campaign, Graham touted his conservative stance on issues such as looking for answers on Benghazi, supporting the military, opposing Obamacare and in support of the Keystone pipeline.

The 59-year-old incumbent has served in the U.S. Senate since 2003, following Strom Thurmond. He also served in the U.S. House 3rd District from 1995 to 2003.

Graham defeated State Sen. Lee Bright, pastor and attorney Det Bowers; small business owner and pro-life activist Richard Cash; attorneys Bill Connor and Benjamin Dunn; and businesswoman and author Nancy Mace. He will be opposed by U.S. Senate Brad Hutto in November.

U.S. Senate – Special election

U.S. Sen. Tim Scott was declared an early winner of a special election with more than 90 percent of the vote over unknown candidate Randall Young, of Greenville, whose campaign and contact information was never made public. Scott will serve the final two years of Jim DeMint's second term.

Lieutenant Governor - GOP

There will be a runoff for the Republican primary for Lieutenant Governor between Henry McMaster and the second place candidate. The second and third place candidates, retired Kiawah Island developer Pat McKinney and Mike Campbell, the son of the late Gov. Carroll Campbell were within a percent of each other, with 24 percent of the vote.

McMaster, who was attorney General of South Carolina from 2003 to 2011, had previous unsuccessful runs for lieutenant governor, governor and U.S. Senate.

McMaster and his opponent will square off June 24.

The GOP winner will face Democratic state Rep. Bakari Sellers in November. The governor and lieutenant governor will start running on the same ticket in 2018.

Anderson County Probate Judge

One of the most hotly contested races in Anderson County was for probate judge, where magistrate Dan Sharp tried unsuccessfully to unseat Martha Newton, who was first elected in 1983.

The GOP winner for Agriculture Commissioner was Hugh Weathers, with more than 66 percent of the vote.

Superintendent of Education - Democrat, GOP

Sheila Gallagher has advanced to a runoff in the Democratic primary for South Carolina's superintendent of education.

Gallagher unofficially received 36 percent of the vote Tuesday night making her the biggest vote getter in the primary.

She will face Tom Thompson, who received 26 percent of the vote, in the runoff.

For the GOP, there will be a runoff between Sally Atwater and Molly Spearman.

State Senator - Democrat

State Sen. Brad Hutto has won South Carolina's Democratic primary for the U.S. Senate

Early returns showed the 56-year-old Hutto winning Tuesday's primary with more than 75 percent of the vote over businessman Jay Stamper.

The state Democratic Party's executive committee voted unanimously last month to endorse Hutto, a repudiation of Stamper, who has felony convictions from 2008 for selling unregistered securities in Nevada.

Adjutant General- GOP

Bob Livingston has defeated his GOP primary challenger in his bid to be re-elected South Carolina's top military officer.

Early returns in Tuesday's primary show Livingston with 77 percent of the vote over 45-year-old James Breazeale. Livingston has no opposition in November.

The adjutant general oversees the state's 11,000-member Army and Air National Guard, State Guard and the state's Emergency Management Division.

The 57-year-old Livingston was elected in 2010 to a four-year term with no opposition.
